Abstract

Two and perhaps three taxa of Lissotriton newt occur in Turkey. Their species status is controversial. The distribution of these taxa and the taxonomic status of each are reviewed and discussed. A database of 128 Turkish Lissotriton localities was compiled and species distribution models were constructed. We reiterate that the presence of L. (v.) lantzi in Turkey is disputed and needs confirmation. The range of L. (v.) kosswigi is restricted to north-western Anatolia – given the small global range of this Turkey endemic, a closer look at its conservation status is warranted. The distribution of L. v. schmidtleri covers western Asiatic and European Turkey. The findings support an allopatric distribution of the Turkish Lissotriton species. We reflect on the biological significance of previously reported morphological intermediates between L. (v.) kosswigi and L. v. schmidtleri in the light of the recent proposal to recognize kosswigi at the species level. The available data are in line with species status for L. (v.) lantzi and L. (v.) kosswigi. Although L. v. schmidtleri is a genetically diverged taxon as well, the extent of gene flow with parapatric European Lissotriton taxa is as yet unknown.
